抄録

Thirty diacylhydrazines with various pair of acyl groups were prepared. Their crystal nucleating activity was obtained by DSC as the crystallization temperature of polypropylene (PP) containing 0.5phr of the diacylhydrazine and 0.5phr of the antioxidant, and 3.0phr of metallic copper powder. Aging lives of films of the polypropylene compositions aged at 150°C were determined. Nucleating activities and aging lives were also measured for PP compositions containing commercial metal deactivators. The additives giving higher crystallizing temperature for polypropylene were found to show longer aging life for polypropylene. Multiple regression equations using physical properties of diacylhydrazines such as melting point, heat of fusion, N-H absorption band, as well as the crystallization temperature of polypropylene were derived.
